The nRF24L01+PA+LNA 2.4GHz  RF Wireless Modules are RF transceiver modules that can be used for wireless communications up to 1100 meters. These modules operate the same as the standard nRF24L01+, but it adds a power amplifier and detachable antenna to give it an extended range of 1100 meters vs the 100 meters of the standard nRF24L01+.  The maximum range will vary depending on data rate chosen , on whether there are obstructions to the signal. The modules operate in the 2.4GHz band at data rates of 250Kbps, 1Mbps or 2Mbps.  Max operating current is < 115mA.


·       The nRF24L01+ is a 2.4GHz ISM band transceiver

·       Range: 800+ meters line of sight (refer to "Important Note" section below)

·       Includes on board support components and the RFX2401C which is the PA (Power Amplifier) and LNA (Low-Noise Amplifier)

·       A host microcontroller can communicate and configure the nRF24L01+ over a 4-pin Serial Peripheral Interface (SPI). The configuration registers are accessible through the SPI connection. Configurable parameters include frequency channel (125 selectable channels), output power, and data rate (data rates: 250kbps, 1Mbps, and 2Mbps).

·       The on chip voltage regulator accepts supply voltages from 1.9 to 3.6V.

·       The module has 5V tolerant inputs which allows for direct connection of SPI pins to the Arduino.

·       Internal filtering results in high margins of meeting RF regulatory standards. The module's radio uses Gaussian Frequency-Shift Keying (GFSK) modulation as well as fast Automatic Gain Control (AGC).

·       The module includes an Interrupt Request (IRQ) pin which can be used to wake the host microcontroller, (ex: Arduino), from sleep when the module receives a transmission providing great power conservation in battery devices.

·       Auto-acknowledge and auto-retransmit abilities

·       Weight: 13.28 g (0.468 oz)

·       Board dimensions, excluding pins: 15.5mm (0.61") width x 40.7mm (1.6") length x 12.2mm (0.48") height

·       Dimensions of antenna, when angled at 90 degrees: 87mm (3.43") height x 9.5mm (0.37") diameter
